Cover board is slidably connected, one end of the cover board is fixedly connected with handle, and the bottom end of the top box is fixedly connected with flexible foam
Sponge, the inside of the flexible foam sponge is interspersed to be connected with air inlet pipe group, and it is mechanical, electrical that the inside of the top box is installed with wind
The bottom of source, signal receiver and controller, the cavity is fixedly connected with exhaust pipe, if the top of the exhaust pipe offers
The exhaust end of dry gas vent, the wind turbine is connected to by pipeline with the exhaust pipe.
Further, the wind turbine is electrically connected with the power supply, and the signal receiver passes through the controller and institute
State power supply electric connection, the bottom end of the flexible foam sponge is fixed with pressure sensor, the pressure sensor with it is described
Signal receiver is electrically connected.
Further, the air inlet pipe group includes several longitudinal tubule (L tubule)s, several transverse tubes and vertical tube, several longitudinal tubule (L tubule)s and several institutes
It states transverse tube intersection connection to reticulate, the vertical tube is connected to any longitudinal tubule (L tubule), and the inlet end of the wind turbine passes through pipeline and institute
State vertical tube connection.
Further, the sponge being placed in the cavity after water suction.
Compared with prior art, the present invention has the advantages that：This kind of automatic dust absorption Environmentally friendly blackboard eraser, by the way that wind is arranged
The dust that machine generates when absorbing using blackboard eraser, can reduce dust and be endangered caused by human body and environment；It is passed by the way that pressure is arranged
Sensor and controller realize that pressure controls power switch, do not have to manual operation, more convenient, intelligence；By using water-absorbing sponge
Absorb dust, it is clean effectively and to be readily cleaned.

Specific implementation mode
To make the technical means, the creative features, the aims and the efficiencies achieved by the present invention be easy to understand, with reference to
Specific implementation mode, the present invention is further explained.
As shown in Figs. 1-3, the side of a kind of automatic dust absorption Environmentally friendly blackboard eraser, including top box 1, top box 1 is equipped with cavity 3, cavity 3
The both sides on top are equipped with sliding-rail groove, and cavity 3 slidably connects cover board 4 by sliding-rail groove, and one end of cover board 4, which is fixedly connected with, to be carried
The bottom end of hand 5, Convenient switch cover board 4, top box 1 is fixedly connected with flexible foam sponge 2, and the inside of flexible foam sponge 2 is interspersed
It is connected with air inlet pipe group 6, the inside of top box 1 is installed with wind turbine 7, power supply 8, signal receiver 9 and controller 10, cavity 3
Bottom be fixedly connected with exhaust pipe 12, the top of exhaust pipe 12 offers several gas vents 13, is uniformly discharged conducive to dust, wind
The exhaust end of machine 7 is connected to by pipeline with exhaust pipe 12, is facilitated and is drained into dust in cavity 3.
Wherein, wind turbine 7 is electrically connected with power supply 8, and signal receiver 9 is electrically connected by controller 10 and power supply 8, soft
The bottom end of foam sponge 2 is fixed with pressure sensor 11, and pressure sensor 11 is electrically connected with signal receiver 9, realizes pressure
Power controls the switch of power supply 8 so that the blackboard eraser is more intelligent.
Wherein, air inlet pipe group 6 includes several vertical poles 15, several cross bars 16 and montant 14, several vertical poles 15 and several cross bars
16, which intersect connection, reticulates, and montant 14 is connected to any vertical pole 15, and the inlet end of wind turbine 7 is connect by pipeline with montant 14, is led to
